Dissolved oxygen is an essential controlling factor in the performance of facultative and maturation ponds since both take many advantages of algal photosynthetic oxygenation. The rate of this photosynthesis strongly depends on the time during the day and the location in a pond system, whose roles have been overlooked in previous guidelines of pond...

Solar disinfection (SODIS) is a very inexpensive and easy-to-run water-treatment process that is widely used in third world countries to decrease the number of waterborne diseases and mortality. However, it does have a number of disadvantages, including the long time needed for complete disinfection, especially during cloudy days, and the possible ...

The project aimed at a better understanding of the mutagenic (and thereby carcinogenic) effects of sunlight (UVB). In particular, the mechanism of the indirect (oxidative) DNA damage and its contribution to the mutagenicity of solar radiation at various wavelengths was to be investigated. In addition, the effects of potential protecants were to be ...
